How to use whatsapp from PC with your number

Hello all, this guide will be a little tricky but here i come.
Requirements
-Android emulator and Android SDK
-An actually rooted android phone with whatsapp installed
-A hex editor (http://portableapps.com/apps/development/frhed_portable)
Steps:

1. Download and install android SDK from http://www.android.com
2. Open SDK Manager and download the same API of your Android phone version, then make a new emulator image with Google apis and 1024MB of sdcard
3. Root your android emulator following this guide: http://abd-tech.blogspot.com/2011/05/test-root-apps-on-android-emulator.html.
   Hint: If "memory full" message appears, just go to /system/apps/ and rm email.apk, then retry
4. Patch your android emulator with your Android phone IMEI number following this guide: http://codepainters.wordpress.com/2009/12/11/android-imei-number-and-the-emulator
   Or open  tools/emulator.exe with the hex editor and substitute +CGSN 000000000000000 with your own imei
   Hint: On newer emulators you should patch tools/emulator-arm.exe
5. Install TitaniumBackup on your Android phone and backup Whatsapp app
6. Install TitaniumBackup on the emulator by downloading it from their website: http://matrixrewriter.com/android/
   Hint: A popup will ask you for su permission
7. Push the Whatsapp backup files from your Android phone to your Emulator /sdcard/TitaniumBackup folder using the command adb push from shell
8. Restore the app with TitaniumBackup (reload it first) and reboot emulator

Here you are! :D Congrats
Remember, you can't use both mobile and emulator at the same time!
